Yes, that's right. There should be more tutorials, guides about fonline modding because many people don't know how to even start. There is already mapper tutorial which is really good but for me it needs more work and should be continued and translated to english. Also some scripts tutorials or maybe course will be great too.
I agree that one of the biggest bottlenecks for getting more developers is good tutorials, it doesn't even have to be long ones, just something to get people started (or hooked, depending on how you look at it) enough to dig deeper on their own. I wrote a dialog guide a few years back and I think or at least hope it was kind of useful to a few people. There's nothing like that for mapping, scripting or using any of the other tools really. At least not in English that I'm a aware of, I know there's a few guides in polish and russian, so translating those could be a start.
I'm afraid it may be too late, as the community seems to be on the decline. But on the other hand there's still modding community around the original Fallouts and games like Morrowind so there's always hope. And the few surviving projects might take off and draw a lot of new players/devs to the community.
I hope more people will open source their work, it could help a lot of people jump starting their own ideas.
